Personalization Not Triggering Correctly

Hi Everyone,

I'm trying to build a personalization that populates asset book in the invoice distributions based on whether or not a DFF field on the PO is populated. This DFF attribute gets copied into the invoice distribution from the PO distributions however it seems that the personalization is triggering before this attribute gets copied into the invoice distribution and so is not populating the asset book. It DOES populate it if I go back into the distribution line and update the record/hit save a 2nd time. Any ideas?

Here's the logic I'm trying to use:

Trigger event: WHEN-VALIDATE-RECORD
